Fixing device
Fixing device for a shaft sealing ring and transmission device having such a device. A fixing device for a shaft sealing ring is disclosed. Furthermore, a transmission device is disclosed, wherein the transmission device comprises a first transmission part which is rotatable about an axis of rotation, a sealing seat formed in the first transmission part, a shaft sealing ring fitted in the sealing seat and a second transmission part which extends through the first transmission part and the shaft sealing ring and is rotatable about the axis of rotation. A sealing lip is formed on the shaft sealing ring, the sealing lip engaging with an outer surface of the second transmission part and being pretensioned by a spring element arranged on the shaft sealing ring. The transmission device also has a fixing device for the shaft sealing ring.
1 . A fixing device for a shaft sealing ring, comprising:
a retaining ring which is rotatable about an axis of rotation and a plurality of pivot bodies arranged pivotably on the retaining ring, wherein each pivot body has a pivot bearing through which the retaining ring extends as a pivot axis,
wherein each of the pivot bodies comprises a first and second pivot arm which each extend from the pivot bearing in opposite directions axially with respect to the axis of rotation such that the retaining ring is arranged between the pivot arms and a deflection of the first pivot arm in a first direction radially with respect to the axis of rotation causes a deflection of the second pivot arm in a direction opposite to the first direction radially with respect to the axis of rotation.
2 . The fixing device of claim 1 , wherein the product of the mass of the first pivot arm and the distance of the mass center of gravity of the first pivot arm from the pivot axis is greater than the product of the mass of the second pivot arm and the distance of the mass center of gravity of the second pivot arm from the pivot axis, and therefore a centrifugal force arising by rotation of the retaining ring about an axis of rotation causes the first pivot arm to be deflected radially outward with respect to the axis of rotation.
3 . The fixing device of claim 1 , wherein the plurality of pivot bodies have a round or circular profile.
4 . The fixing device of claim 1 , wherein the plurality of pivot bodies comprise a metal material.
5 . The fixing device of claim 4 , wherein the plurality of pivot bodies comprise a cast-iron material.
6 . The fixing device of claim 1 , wherein the first pivot arm is in the form of a cylindrical extent and the second pivot arm is in the form of a T-shaped extent.
7 . The fixing device of claim 1 , wherein the plurality of pivot bodies are coupled to the retaining ring via an opening formed between the ends of the retaining ring, and the plurality of pivot bodies are pivotably suspended or pivotably mounted on the retaining ring.
8 . The fixing device of claim 1 , wherein the second pivot arm has a pivot arm part formed parallel along the pivot axis, and a retaining groove is formed on the side of the pivot arm part that is facing the axis of rotation of the pivot arm part.
